The symptoms of cocaine overdose include:
- Excessive anxiety
- Restlessness, an inability to sit still or stop moving
- Paranoia
- Rapid, rambling speech
- Sudden spikes in blood pressure
- Fever
- Nausea and vomiting
- Shaking, tremors
- Extreme mental confusion
- Irregular heartbeat
- Psychotic episodes (delusions, hallucinations, feelings of detachment from reality, etc.)
A cocaine overdose produces effects that are highly unpleasant and alarming, and require emergency medical attention. If the symptoms of cocaine overdose are ignored, the person could suffer a seizure, heart attack, or stroke, and their condition could ultimately prove fatal.
